* Based on the 2006-07 TUS-CPS questions: a) Have you smoked at least 100
cigarettes in your entire life? and b) Do you now smoke cigarettes every day, some days,
or not at all? Current smoking is therefore represented as the sum of Everyday and
Some-day smoking. Former smokers are defined as those who have smoked 100 or more
cigarettes, but who were no longer smoking at the time of the interview, and Never smokers
were defined as those who had smoked less than 100 cigarettes in their lifetime.

† Current = Every Day + Some Days

‡ In the 2006-07 CPS, multiple races were allowed. Here "White" equals
non-Hispanic, only White race reported; "Black" equals non-Hispanic, only Black race
reported; "American Indian/Alaska Native" equals non-Hispanic, only American Indian/Alaska
Native race reported; "Asian/Pacific Islander" equals non-Hispanic, only Asian/Native
Hawaiian & Other Pacific Islander race reported; "2 or more races reported" equals
non-Hispanic, 2 or more races reported. Note more than half of this last category is
composed of non-Hispanic American Indian/Alaska Natives also reporting one or more other
races. Also, non-Hispanic Asian/Native Hawaiian & Other Pacific Islanders reporting some
other race(s) make up the next largest subcategory within this grouping (mainly the Native
Hawaiian & Other Pacific Islanders).

§ For analysis involving educational level, only respondents 25 or older are
included, as many respondents between 18 and 24 have not yet completed formal
education/training.
